Once upon a time I installed Knoppmyth on a laptop.  Couldn't get it to 
initialize the display properly, the whole screen would be compressed onto the 
left half of the laptop display.  But when an external monitor was plugged in, 
it would boot to the laptop display just fine.

So I made a vga monitor emulator, which was from memory three resistors and a 
wire link soldered into a 15 pin sub-din connector, which when left plugged 
into the laptop's vga port fooled it into thinking there was an external 
monitor plugged in, and it would boot fine.

In these days of graphics card crypto-currency mining, monitor emulators seem 
to be readily available and may solve your problem of a monitor needing to be 
plugged in.
